Oswaldo “Ozzie” Grenardo, MD, MBA, MSHA, FAAFP

Dr. Oswaldo "Ozzie" Grenardo leads OG Health, a direct primary care practice in Greenwood Village. He brings more than 25 years of executive, clinical, and academic medical experience to his patients, having served as a chief medical officer and a dean of admissions earlier in his career.

At OG Health, he keeps his patient panel small so each person gets real time, attention, and advocacy rather than a rushed visit and a long wait. Access matters to him, and he offers direct, year-round reach along with proactive, whole-person care that helps patients navigate the healthcare system with ease.

Trust and continuity anchor how he practices medicine. His patients also benefit from smooth scheduling, strong communication, and modern diagnostic tools and platforms that help the practice stay ahead of their needs.
